How the Illinois Paycheck Calculator Works
The calculator annualizes taxable regular wages and subtracts $2,925 for each entered Illinois exemption allowance plus any additional state deduction.
It multiplies the nonnegative balance by 4.95% and divides by the selected number of pay periods.
Illinois withholding = max(0, annual taxable wages − allowances × $2,925 − state deduction) × 4.95% ÷ pay periods
Example
For $52,000 annual taxable wages and one allowance, estimated Illinois withholding is ($52,000 − $2,925) × 4.95% = $2,429.21 annually.
